These 2d horizons are topologically punctured two-sphere s\, with at least two punctures\, and are equipped with non-constant curva ture metrics. They arise when considering the near-horizon limit of extrem al asymptotically AdS accelerating black holes. Interestingly\, despite th e black hole solutions having singularities\, by uplifting the solutions t o string theory the solution can be made singularity free in certain cases . By using AdS/CFT we have a complimentary dual field theory perspective. The near-horizon geometry corresponds to the fixed point of an RG-flow acr oss dimensions\, triggered by wrapping a parent theory on the 2d horizon. As we will show\, in order for the fixed point to preserve supersymmetry\ , the introduction of new and novel twists of the theory is required. We w ill make some comments on performing a microstate computation of the entro py of the black hole.\n LOCATION:https://researchseminars.org/talk/ATP2022/14/ END:VEVENT END:VCALENDAR
